Marvel’s new-comics list for 21 October 2026 is led by Amazing Spider-Man: Halloween Special #1 and Avengers: Armageddon #5. The official weekly list gives readers a timely mixture of seasonal Spider-Man, event-scale Avengers action and continuing series.

The headline issues

Amazing Spider-Man: Halloween Special (2026) #1 is the calendar-perfect entry. Seasonal one-shots often attract readers who are not following every monthly chapter, while their self-contained positioning can make them appealing display pieces for collectors.

Avengers: Armageddon (2026) #5 continues Marvel’s event storyline. Collectors following the complete run should confirm issue number and cover before ordering, particularly where retailers offer multiple variants.

Marvel’s official list also names Doomquest #5, Inglorious X-Force #10 and a new Iron Man release among this week’s shelf arrivals. Availability and cover selection will vary by comic shop.

A collector’s checklist

• Decide whether you want a reading copy, a favourite variant, or both.
• Check the indicia and issue number rather than relying only on cover art.
• Ask your comic shop whether ratio variants are allocated or sold separately.
• Store bagged comics upright with suitable backing boards and away from direct sunlight.
• Do not treat a cover price or online asking price as proof of future value.

Weekly release lists can change, so check with your local retailer before making a special journey. Readers hunting across franchises can also explore ASACC’s Franchise directory and marketplace.
